1. First Embodiment

(1-1. Example of Configuration)

First, a schematic configuration of a portable terminal 100 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 and 2. FIG. 1 is an explanatory diagram illustrating an example of an external appearance of the portable terminal according to the first embodiment of the present disclosure. FIG. 2 is a functional block diagram of the portable terminal according to the same embodiment.

As illustrated in FIG. 1, the portable terminal 100 includes a display unit 103 on a surface of a case, and a touch sensor 105 overlapping the display unit 103. Also, the portable terminal 100 may also be combined with a manipulation unit by a button or the like, separately from the touch sensor. Due to such a configuration, the portable terminal 100 may receive a user input by a position of a manipulation body on a display screen displayed on the display unit 103. In addition, the portable terminal 100 may use a so-called Graphical User Interface (GUI) to control contents of the display screen based on the user input.

The portable terminal 100 is an example of an information processing apparatus in which manipulability from a locked state to an application start-up manipulation is improved. For example, the portable terminal 100 may be a portable phone including a smart phone, and may also be an information processing apparatus, such as a portable music reproduction apparatus, a portable video processing apparatus, a portable game machine, a notebook Personal Computer (PC), a tablet type PC, or the like. In addition, although a portable terminal device is exemplarily described herein, the present technology may be applied to all information processing apparatuses having a locking function. While the above description explains a situation where the application is executed on the device, the unlock operation may also be to used to trigger the execution of an application hosted on a remote processor. Moreover, the terminal device may communication a trigger signal to a remote device, in response to the user's interaction on the local device.

The portable terminal 100, as illustrated in FIG. 2, is an information processing apparatus that mainly includes a display unit 103, a touch sensor 105, and a control unit 107. Also, although a configuration for describing the function of the portable terminal 100 according to the same embodiment will be mainly described herein, the portable terminal 100 may be an information processing apparatus having various other functions. An example of a hardware configuration of the portable terminal 100 will be described later.

The display unit 103 is an example of an output device and may be a display device, such as a liquid crystal display (LCD) device, an organic light emitting diode (OLED) display device, or the like.

The touch sensor 105 is an example of an input unit and is an example of a detection unit that detects a position of a manipulation body on a sensor. Herein, since the touch sensor 105 is installed to overlap the display unit 103 that displays a display screen, the touch sensor 105 may detect a position of the manipulation body on the display screen. Also, the touch sensor 105 used herein may be a contact type sensor that detects the position of the manipulation body in contact with a surface of a detection surface side of the touch sensor 105 in the case. Alternatively, the touch sensor 105 may also be a contactless type sensor that detects the position of the manipulation body over the detection surface of the sensor. The manipulation body that performs an input manipulation on the touch sensor 105 may be, for example, a user's finger. Alternatively, the manipulation body may be a stylus.

The control unit 107 has a function of controlling the overall operation of the portable terminal 100. For example, the control unit 107 may function as a display control unit that controls contents of the display screen to be displayed on the display unit 103 based on position information of the manipulation body input from the touch sensor 105. In addition, for example, when the display unit 103 displays a display screen, including icons of applications, and a user's manipulation of selecting the displayed icons is detected, the control unit 107 may start up the applications corresponding to the selected icons. Moreover, the control unit 107 may control operations of the respective started applications.

Control contents of the control unit 107 with respect to a manipulation from a locked state to an application start-up in the present embodiment herein will be described. In addition, the locking as mentioned herein means a function of restricting a user input. When in the locked state, for example, user manipulations other than a predetermined manipulation are entirely invalidated. An example of the predetermined manipulation includes an unlock manipulation, an emergency notification manipulation, or the like. A transition to the locked state is performed, for example, in the case in which a non-manipulation state has continued for a predetermined period of time, a case in which a predetermined lock start-up manipulation is performed by a user, or the like. Such a configuration may prevent an input contrary to a user's intention from being performed.

When a first manipulation is performed on the display screen in the locked state, the control unit 107 arranges icons with reference to a point (reference point) indicating the position of the manipulation body when the first manipulation is completed. Herein, it is preferable that the icons be arranged at a position where one icon is specified with respect to a direction from the reference point. For example, the icons may be arranged radially around the reference point. Also, the icons may also be arranged in a row. When the user performs a second manipulation indicating the direction from the reference point, the control unit 107 may start up an application corresponding to an icon specified by the second manipulation. Also, herein, the first manipulation in the present embodiment is a manipulation (for example, a press-and-hold manipulation) indicating an arbitrary point on a display screen over a predetermined period of time. Also, the second manipulation is a drag manipulation indicating one direction from the reference point.

The control unit 107 also has a function as a selection unit that selects icons to be displayed herein. The control unit 107, for example, may select icons to be displayed in units of a set of pre-selected icons. Alternatively, the control unit 107 may create a set of icons to be displayed by selecting icons one by one. In the present embodiment, the control unit 107 displays a set of pre-selected icons on the display screen. The set of icons, for example, may be a set of icons pre-selected by the user. Alternatively, the set of icons may be a set of icons pre-selected before shipment of the portable terminal 100. When a position corresponding to a reference point, at which each icon among a set of icons prepared beforehand is to be displayed, is predetermined, the user may perform an icon selection manipulation without looking at the display screen, and thus there is an effect of improving manipulability. In addition, the control unit 107 may also select a set of icons to be displayed based on the position of the reference point on the display screen. For example, a case in which an upper half area of the display screen is predetermined as an area for starting up a utility application and a lower half area of the display screen is predetermined as an area for starting up a social application is assumed. In this case, when a position of a press-and-hold manipulation detected by the touch sensor is the upper half area of the display screen, the control unit 107 may display a set of icons corresponding to the utility application.

Also, when displaying the icons, the control unit 107 may display the number of new information of the applications corresponding to the respective icons. According to such a display, the user may know the presence/absence and the number of the new information, without starting up the applications. For example, in the case of a mail application, the new information may be the number of unread mails. Alternatively, in the case of an application for connection to a social networking service, the new information may be the number of notifications of new postings and mails, or the like.

The example of the functions of the portable terminal 100 according to the present embodiment has been shown above. The respective elements described above may be configured using general-purpose members or circuits, or may be configured by hardware specialized in the functions of the respective elements. Also, an arithmetic device, such as a central processing unit (CPU) or the like, may perform the functions of the respective elements by reading a control program from a storage medium, such as a read only memory (ROM), a random access memory (RAM), or the like, which stores the control program describing a processing procedure of realizing these functions, and by interpreting and executing the program. Therefore, the configuration to be used may be appropriately modified depending on a level of technology when the present embodiment is implemented. Also, an example of a hardware configuration of the portable terminal 100 will be described later.

Also, a computer program for realizing the respective functions of the portable terminal 100 according to the present embodiment described above may be created and implemented on a personal computer or the like. Also, a computer-readable recording medium on which such a computer program is stored may also be provided. The recording medium may be, for example, a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, or the like. Also, the computer program may also be delivered through a network without using the recording medium.

(1-2. Example of Display Screen)

Next, an example of a display screen displayed on the display unit 103 of the portable terminal 100 will be described with reference to FIGS. 3 to 7. FIG. 3 is an explanatory diagram illustrating an example of a manipulation on a display screen according to the same embodiment. FIG. 4 is an explanatory diagram for describing another example of an icon display according to the same embodiment. FIG. 5 is an explanatory diagram for describing an example of a home screen start-up according to the same embodiment. FIG. 6 is an explanatory diagram for describing another example of an icon display according to the same embodiment. FIG. 7 is an explanatory diagram for describing an example of selecting an icon to be displayed based on a touch position according to the same embodiment.

Also, in the present specification and drawings, there are cases in which a plurality of elements having substantially the same functional configuration are distinguished by assigning different letters or numerals after the same reference sign. For example, a plurality of elements having substantially the same functional configuration, if necessary, are distinguished as in an icon Ia and an icon Ib. However, if each of a plurality of elements having substantially the same functional configuration need not be especially distinguished, only the common reference sign is assigned thereto. For example, if an icon Ia, an icon Ib, and the like, need not be especially distinguished, the icons are simply referred to as icons I.

First, an example of a display screen at the time of unlocking the portable terminal 100 according to the present embodiment will be described with reference to FIG. 3. As illustrated in FIG. 3(A), the user touches an arbitrary point of a display screen 10 in a locked state with a finger (example of a manipulation body) and performs a so-called press-and-hold manipulation of maintaining the position P1 of the finger over a predetermined period of time. Then, as illustrated in FIG. 3(B), the control unit 107 radially arranges icons I around the position P1 of the finger detected on the display screen 10.

Herein, for example, an icon Ia for starting up a mail application, an icon Ib for starting up an imaging application, an icon Ic for starting up an application to connect to a short web log service, and an icon Id and an icon Ie for starting up application to connect to social network services (SNSs) are displayed radially. If the user performs a drag manipulation in a direction toward one of the displayed icons I, the control unit 107 starts up an application corresponding to an icon specified by the drag manipulation. In the example of FIG. 3(C), the user performs a drag manipulation in a direction toward the icon Ib corresponding to the imaging application, as indicated by an arrow. Therefore, the control unit 107 starts up the imaging application corresponding to the icon Ib.

The icons I displayed herein, for example, may be a set of icons I predetermined before shipment of the portable terminal 100. Alternatively, the displayed icons I may be a set of icons I corresponding to applications selected by the user. The user may pre-select an application that is frequently used. Also, in this case, the user may also preset positions at which the respective icons I are to be displayed. When the user knows in advance positions at which the icons I are to be displayed corresponding to the position P1 of the finger, the user may perform an unlock to an application start-up without looking at the display screen 10. The user need only perform a press-and-hold manipulation at an arbitrary position on the display screen 10 and perform a drag manipulation in a direction of the icons I of an application to be started up. Due to such a manipulation, the unlock and the application start-up may be performed by a series of manipulations in which the user does not release the finger from the screen.

For example, as the user interface that performs the unlock and the application start-up by a series of manipulations, a display screen 91 and a display screen 93 illustrated in FIGS. 24 and 25 are suggested. For example, on the display screen 91 illustrated in FIG. 24, by dragging one of displayed icons I, for example, an icon 18, to the right and sliding the icon 18 to the right edge of the screen, the user may start up an application corresponding to the manipulated icon 18. Also, similarly, on the display screen 93 illustrated in FIG. 25, by dragging one of displayed icons I, for example, an icon 19, to the right or left, an application corresponding to the manipulated icon 19 may be started up. However, in the examples illustrated in FIGS. 24 and 25, the user should look at and perceive the entire display screen. On the other hand, the display screen 10 of the present embodiment displays the icons I radially around an arbitrary point the user touches. Therefore, the user need only look at the periphery of the position P1 that his or her own finger touches. Therefore, manipulability in the unlock and the application start-up is improved. Moreover, if the position at which the icon I is to be displayed corresponding to the position P1 of the finger is predetermined, the user may perform the manipulation without looking at the screen. Hence, manipulability is further improved.

Also, if the touch position is close to the edge of the display screen 10, as illustrated in FIG. 4(A), the control unit 107 may arrange the icons I in a semicircle. Alternatively, as illustrated in FIG. 4(B), the control unit 107 may arrange the icons I in a column. Herein, although an example of arranging the icons I in a vertical column is illustrated, the present technology is not limited to such an example. The icons I may also be arranged in a horizontal row.

Also, for example, as illustrated in FIG. 5(A), if the drag manipulation is performed in a direction in which there are no icons I, the control unit 107 may start up a home application. Alternatively, as illustrated in FIG. 5(B), the control unit 107 may display a home icon I0 for starting up the home application. If the home icon I0 is specified by the drag manipulation, the control unit 107 may start up the home application.

Also, as illustrated in FIG. 6, the control unit 107 may display the number of new information on the applications corresponding to the respective icons I displayed on the display screen 10, together with the icons I. Also, the control unit 107 may display contents of the new information (for example, part of a mail text) on the display screen 10.

Also, as illustrated in FIG. 7(A), the display screen 10 may be divided into a first area 11 and a second area 13. In the first area 11 and the second area 13, types of icons I displayed when manipulations are performed are different from each other. For example, the first area 11 may be an area for starting up a utility application. In the example of FIG. 7, if a press-and-hold manipulation is detected in the first area 11, an icon Ia for starting up a mail application, an icon If for starting up a call application, an icon Ig for starting up a music reproduction application, an icon Ih for starting up an application for a train transfer guide, and an icon Ii for starting up a calendar application are displayed radially around a position of a finger. Also, the second area 13 may be an area for starting up a social application. In the example of FIG. 7, if a press-and-hold manipulation is detected in the second area 13, an icon Ic for starting up an application to connect to a short web log service, an icon Ij for starting up an application to connect to a social service that shares information related to position information, an icon Ik for starting up an application to connect to a social service that shares images, and an icon Il and an icon Ie for starting up an application to connect to an SNS are displayed radially from a position of a finger.

Due to such a configuration, an option for the applications to be started up may be increased. As the number of icons I displayed radially from the position of the finger at a time is increased, an option for the applications to be started up may be increased. However, in this case, since the option is increased and a risk of an erroneous manipulation is high, manipulability is degraded. On the other hand, the method of the present embodiment, which changes the types of the icons I to be displayed in the areas, may increase the option without changing the risk of the erroneous manipulation, leading to an improvement in manipulability.

(1-3. Example of Operation)

Next, an example of an operation of starting up an application from a locked state of the portable terminal 100 according to the present embodiment will be described with reference to FIG. 8. FIG. 8 is a flow chart illustrating an example of an operation of the portable terminal according to the same embodiment.

First, the control unit 107 determines whether or not a screen touch is detected by the touch sensor 105 (S101). If the screen touch is detected, then the control unit 107 determines whether or not a manipulation of pressing and holding the detected touch position without changing over a predetermined period of time is detected (S103). If the press-and-hold manipulation is detected in step S103, the control unit 107 displays icons I based on the detected touch position (S105). Herein, the icons I, for example, may be displayed radially from the touch position.

Then, the control unit 107 determines whether or not a drag manipulation indicating a direction is detected within a predetermined period of time (S107). If the drag manipulation is detected within the predetermined period of time, the control unit 107 starts up an application depending on the direction of the drag manipulation (S109). For example, if one icon I is specified by the drag manipulation, the control unit 107 may start up an application corresponding to the specified icon I. In addition, if no icons I are specified by the drag manipulation, the control unit 107 may start up a home application.

2. Second Embodiment

Next, a second embodiment of the present disclosure will be described. As compared with the first embodiment, the second embodiment is different in a method of selecting icons to be displayed. In the following description, the differences will be mainly described and the common configuration will not be described.

(2-1. Example of Configuration)

First, a schematic configuration of a portable terminal 200 according to a second embodiment of the present disclosure will be described with reference to FIG. 9. FIG. 9 is a functional block diagram of the portable terminal according to the second embodiment of the present disclosure.

As illustrated in FIG. 9, the portable terminal 200 according to the second embodiment of the present disclosure mainly includes a display unit 103, a touch sensor 105, a control unit 207, and a position information acquisition unit 209.

The control unit 207 has a function of controlling the overall operation of the portable terminal 200. For example, the control unit 207 may function as a display control unit that controls contents of a display screen to be displayed on the display unit 103 based on position information of a manipulation body input from the touch sensor 105. Also, in this case, the control unit 207 may control contents of the display screen using current position information input from the position information acquisition unit 209. Also, in this case, the control unit 207 may control contents of the display screen using information on a current date, day of the week, time, or the like. In addition, when the display unit 103 displays a display screen, including icons I of applications, and the user's manipulation of selecting the displayed icons is detected, the control unit 207 may start up the applications corresponding to the selected icons. Moreover, the control unit 207 may control operations of the respective started applications.

The position information acquisition unit 209 has a function of acquiring position information of a current location. The position information acquisition unit 209 may be realized by, for example, a global positioning system (GPS) antenna and a GPS processing unit that calculates position information from a GPS reception signal. Alternatively, the position information acquisition unit 209 may have a function of measuring a relative position through a variety of sensors. Also, the position information acquisition unit 209 may estimate a distance between each base station and the portable device 200 from reception strengths of Wi-Fi waves received from a plurality of base stations, and may use the estimated distance and the position information of each base station to calculate the current position information based on the principle of triangulation. Also, the position information acquisition unit 209 may acquire the position information by a variety of indoor positioning technologies. For example, examples of technologies used for indoor positioning may include an indoor messaging system (IMES), also called an indoor GPS, visible light communication, infrared communication, a radio frequency identification (RFID) tag, a quick response (QR) code, or the like.

The example of the functions of the portable terminal 200 according to the present embodiment has been shown above. The respective elements described above may be configured using general-purpose members or circuits, or may be configured by hardware specialized in the functions of the respective elements. Also, an arithmetic device, such as a central processing unit (CPU) or the like, may perform the functions of the respective elements by reading a control program from a storage medium, such as a read only memory (ROM), a random access memory (RAM), or the like, which stores the control program describing a processing procedure of realizing these functions, and by interpreting and executing the program. Therefore, the configuration to be used may be appropriately modified depending on a level of technology when the present embodiment is implemented. Also, an example of a hardware configuration of the portable terminal 200 will be described later.

Also, a computer program for realizing the respective functions of the portable terminal 200 according to the present embodiment described above may be created and implemented on a personal computer or the like. Also, a computer-readable recording medium on which such a computer program is stored may be provided. The recording medium may be, for example, a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, or the like. Also, the computer program may also be delivered through a network without using the recording medium.

(2-2. Example of Display Screen)

Next, an example of a display screen displayed on the display unit 103 of the portable terminal 200 will be described with reference to FIGS. 10 to 12. FIG. 10 is an example of a display screen displayed when a user is in a company, according to the same embodiment. FIG. 11 is an example of a display screen displayed when it is determined that a user is on vacation, according to the same embodiment. FIG. 12 is an example of a display screen displayed when a user is on a train, according to the same embodiment.

For example, as illustrated in FIG. 10, in the case in which the touch sensor 105 detects a press-and-hold manipulation, if position information input from the position information acquisition unit 209 indicates that a user is in a company, the control unit 207 may display a set of icons I selected based on the position information. In this case, the set of the displayed icons I may be, for example, a set of icons I pre-selected for when the user is in a company. It is preferable that the set of the icons I corresponds to applications that are frequently used when in a company. For example, in the example of FIG. 10, an icon Ia for starting up a mail application, an icon Ii for starting up a calendar application, an icon Ih for starting up an application for a train transfer guide, an icon In for starting up a map application, and an icon If for starting up a call application are displayed. Also, in this case, the control unit 207 may further select a set of icons to be displayed using information on the current date, day of the week, or the like. For example, when it is detected that the user is in a company, a set of icons I different from the above may be displayed if it is a holiday or it is a time slot other than a fixed time.

Also, as illustrated in FIG. 11, when the touch sensor 105 detects a press-and-hold manipulation, if position information input from the position information acquisition unit 209 indicates that a user is in a travel destination, the control unit 207 may display a set of icons I selected based on the position information. In this case, the set of the displayed icons I may be, for example, a set of icons I pre-selected for when the user is in a travel destination. It is preferable that the set of the icons I corresponds to applications that are thought to be frequently used when in a travel destination. For example, in the example of FIG. 11, an icon Io for starting up an application to view weather information, an icon Ig for starting up a music reproduction application, an icon Ip for starting up a web browser application, and an icon Ir for starting up a book browser application are displayed. Also, the control unit 207 may determine that the user is in a travel destination using information on a user's schedule in addition to the position information or instead of the position information.

Also, as illustrated in FIG. 12, when the touch sensor 105 detects a press-and-hold manipulation, if position information input from the position information acquisition unit 209 indicates that a user is on a train, the control unit 207 may display a set of icons I selected based on the position information. It is preferable that the set of the displayed icons I corresponds to applications that are thought to be frequently used on a train. In the example of FIG. 12, an icon Ir for starting up a book browser application, an icon Ig for starting up a music reproduction application, an icon Ii for starting up a calendar application, an icon Ie for starting up an application to connect to an SNS, and an icon Iq for starting up a video replay application are displayed. Also, for example, if the position information detects a movement on rails, the control unit 207 may determine that the user is on a train when it may be determined that the moving speed is movement by a train. Alternatively, in order to determine that the user is on the train, the control unit 207 may use detection values from sensors, such as a gyro sensor and an acceleration sensor, in combination.

(2-3. Example of Operation)

Herein, an example of an operation in an unlock and an application start-up of the portable terminal 200 according to the present embodiment will be described with reference to FIG. 13. FIG. 13 is a flow chart illustrating an example of an operation of the portable terminal according to the same embodiment.

First, the control unit 207 determines whether or not a screen touch is detected by the touch sensor 105 (S201). If the screen touch is detected, the control unit 207 then determines whether or not a manipulation of pressing and holding the detected touch position without changing over a predetermined period of time is detected (S203). If the press-and-hold manipulation is detected in step S203, the control unit 207 then acquires position information of a current location in the position information acquisition unit 209 and selects a set of icons to be displayed based on the acquired position information (S204). Then, the control unit 207 displays the selected icons I at positions based on the detected touch position (S205). Herein, the icons I, for example, may be displayed radially from the touch position.

Then, the control unit 207 determines whether or not a drag manipulation is detected within a predetermined period of time (S207). If the drag manipulation is detected within the predetermined period of time, the control unit 207 starts up an application depending on the direction of the drag manipulation (S209). For example, if one icon I is specified by the drag manipulation, the control unit 207 may start up an application corresponding to the specified icon I. In addition, if no icons I are specified by the drag manipulation, the control unit 207 may start up a home application.

As described above, according to the configuration of the portable terminal 200 according to the second embodiment of the present disclosure, a set of icons I to be displayed may be selected based on the position information. An application the user wants to start up is different depending on the user's state. Since the user's position greatly affects the user's state, selecting the icons to be displayed based on the position information is effective for the user to start up a desired application quickly.

3. Third Embodiment

Next, a third embodiment of the present disclosure will be described. As compared with the first embodiment and the second embodiment, the third embodiment is different in a method of selecting icons to be displayed. In the following description, the differences will be mainly described and the common configuration will not be described.

(3-1. Example of Configuration)

First, a schematic configuration of a portable terminal 300 according to a third embodiment of the present disclosure will be described with reference to FIG. 14. FIG. 14 is a functional block diagram of the portable terminal according to the third embodiment of the present disclosure.

As illustrated in FIG. 14, the portable terminal 300 according to the third embodiment of the present disclosure mainly includes a display unit 103, a touch sensor 105, a control unit 307, a position information acquisition unit 209, and a behavior recognition unit 311.

The behavior recognition unit 311 has a function of recognizing a user's behavior. For example, the behavior recognition unit 311 may recognize the user's behavior using current position information acquired by the position information acquisition unit 209 and detection values acquired by the gyro sensor, the acceleration sensor, or the like. For example, the behavior recognition unit 311 may recognize that the user is jogging. The behavior recognition unit 311 may provide the recognition result to the control unit 307.

The control unit 307 has a function of controlling the overall operation of the portable terminal 300. For example, the control unit 307 may function as a display control unit that controls contents of a display screen to be displayed on the display unit 103 based on position information of a manipulation body input from the touch sensor 105. Also, in this case, the control unit 307 may control contents of the display screen based on a user's behavior provided from the behavior recognition unit 311. For example, when the behavior recognition unit 311 recognizes that the user is jogging, the control unit 307 may display icons I corresponding to applications frequently used while jogging on the display screen.

The example of the functions of the portable terminal 300 according to the present embodiment has been shown above. The respective elements described above may be configured using general-purpose members or circuits, or may be configured by hardware specialized in the functions of the respective elements. Also, an arithmetic device, such as a central processing unit (CPU) or the like, may perform the functions of the respective elements by reading a control program from a storage medium, such as a read only memory (ROM), a random access memory (RAM), or the like, which stores the control program describing a processing procedure of realizing these functions, and by interpreting and executing the program. Therefore, the configuration to be used may be appropriately modified depending on a level of technology when the present embodiment is implemented. Also, an example of a hardware configuration of the portable terminal 300 will be described later.

Also, a computer program for realizing the respective functions of the portable terminal 300 according to the present embodiment described above may be created and implemented on a personal computer or the like. Also, a computer-readable recording medium on which such a computer program is stored may also be provided. The recording medium may be, for example, a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, or the like. Also, the computer program may also be delivered through a network without using the recording medium.

(3-2. Example of Display Screen)

Next, an example of a display screen displayed on the display unit 103 of the portable terminal 300 will be described with reference to FIG. 15. FIG. 15 is an example of a display screen displayed when a user is jogging, according to the same embodiment.

For example, as illustrated in FIG. 15, when the touch sensor 105 detects a press-and-hold manipulation, if a recognition result provided from the behavior recognition unit 311 indicates that a user is jogging, the control unit 307 may display a set of icons I selected based on the recognition result. In this case, the set of the displayed icons I may be, for example, a set of icons I pre-selected in order to be displayed during jogging. It is preferable that the set of the icons I corresponds to applications that are thought to be frequently used while jogging. For example, in the example of FIG. 15, an icon Ig for starting up a music reproduction application, an icon Is for starting up a route guidance application, and an icon It for starting up a jogging support application are displayed.

(3-3. Example of Operation)

Herein, an example of an operation in an unlock and an application start-up of the portable terminal 300 according to the present embodiment will be described with reference to FIG. 16. FIG. 16 is a flow chart illustrating an example of an operation of the portable terminal according to the same embodiment.

First, the control unit 307 determines whether or not a screen touch is detected by the touch sensor 105 (S301). If the screen touch is detected, the control unit 307 then determines whether or not a manipulation of pressing and holding the detected touch position without changing over a predetermined period of time is detected (S303). If the press-and-hold manipulation is detected in step S303, the control unit 307 then acquires a behavior recognition result from the behavior recognition unit 311 and selects a set of icons to be displayed based on the acquired recognition result (S304). Then, the control unit 307 displays the icons I based on the detected touch position (S305). Herein, the icons I, for example, may be displayed radially from the touch position.

Then, the control unit 307 determines whether or not a drag manipulation indicating a direction is detected within a predetermined period of time (S307). If the drag manipulation is detected within the predetermined period of time, the control unit 307 starts up an application depending on the direction of the drag manipulation (S309). For example, if one icon I is specified by the drag manipulation, the control unit 307 may start up an application corresponding to the specified icon I. In addition, if no icons I are specified by the drag manipulation, the control unit 307 may start up a home application.

As described above, according to the configuration of the portable terminal 300 according to the third embodiment of the present disclosure, a set of icons I to be displayed may be selected based on the behavior recognition result. An application the user wants to start up is different depending on the user's state. If the behavior recognition technology is used, the user's state may be recognized more accurately than the second embodiment in which the user's state is estimated simply based on the position information. Therefore, selecting the icons to be displayed based on the behavior recognition result is effective for the user to start up a desired application quickly.

4. Fourth Embodiment

Next, a fourth embodiment of the present disclosure will be described. The fourth embodiment is different from the first to third embodiments in that icons to be displayed have different configurations depending on a direction of a case of a portable terminal. In the following description, the differences will be mainly described and the common configuration will not be described.

(4-1. Example of Configuration)

First, a schematic configuration of a portable terminal 400 according to a fourth embodiment of the present disclosure will be described with reference to FIG. 17. FIG. 17 is a functional block diagram of the portable terminal according to the fourth embodiment of the present disclosure.

As illustrated in FIG. 17, the portable terminal 400 according to the fourth embodiment of the present disclosure mainly includes a display unit 103, a touch sensor 105, a control unit 407, and a case direction detection unit 413.

The case direction detection unit 413 is, for example, a triaxial acceleration sensor, and may detect a direction of a case. For example, herein, a direction in which a longitudinal direction of the case is generally horizontal may be referred to as sideways. On the other hand, a direction in which a transverse direction of the case is generally horizontal may be referred to as vertical. The case direction detection unit 413 may provide the detected direction of the case to the control unit 407.

The control unit 407 has a function of controlling the overall operation of the portable terminal 400. For example, the control unit 407 may function as a display control unit that controls contents of a display screen to be displayed on the display unit 103 based on position information of a manipulation body input from the touch sensor 105. Also, in this case, the control unit 407 may control contents of the display screen based on the direction of the case provided from the case direction detection unit 413. For example, when the case direction detection unit 413 detects that the case is held sideways, the control unit 407 may display icons I for starting up applications that are frequently used sideways.

Also, it is obvious that the portable terminal 400 may include the combination of the configurations described in the first to third embodiments. For example, the portable terminal 400 may display at least one of the number of new information and a part of contents on a screen displaying icons I. Also, the portable terminal 400 may divide the display screen into a plurality of areas and display different icons I in each area. Also, the portable terminal 400 may further include the configuration of the position information acquisition unit 209 and select icons I to be displayed based on the acquired position information. Alternatively, the portable terminal 400 may include the configuration of the behavior recognition unit 311 and select icons I to be displayed based on the acquired recognition result.

The example of the functions of the portable terminal 400 according to the present embodiment has been shown above. The respective elements described above may be configured using general-purpose members or circuits, or may be configured by hardware specialized in the functions of the respective elements. Also, an arithmetic device, such as a central processing unit (CPU) or the like, may perform the functions of the respective elements by reading a control program from a storage medium, such as a read only memory (ROM), a random access memory (RAM), or the like, which stores the control program describing a processing procedure of realizing these functions, and by interpreting and executing the program. Therefore, the configuration to be used may be appropriately modified depending on a level of technology when the present embodiment is implemented. Also, an example of a hardware configuration of the portable terminal 400 will be described later.

Also, a computer program for realizing the respective functions of the portable terminal 400 according to the present embodiment described above may be created and implemented on a personal computer or the like. Also, a computer-readable recording medium on which such a computer program is stored may also be provided. The recording medium may be, for example, a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, or the like. Also, the computer program may also be delivered through a network, without using the recording medium.

(4-2. Example of Display Screen)

Next, an example of a display screen displayed on the display unit 103 of the portable terminal 400 will be described with reference to FIG. 18. FIG. 18 is an example of a display screen displayed when the portable terminal is held sideways, according to the same embodiment.

For example, as illustrated in FIG. 18, when the touch sensor 105 detects a press-and-hold manipulation, if the direction of the case provided from the case direction detection unit 413 indicates that the case is held sideways, the control unit 407 may display a set of icons I selected based on the direction of the case. In this case, it is preferable that the set of the icons I to be displayed corresponds to applications that are frequently used when the case is held sideways. For example, in the example of FIG. 18, an icon Ib and an icon Iu for starting up imaging applications, an icon Iv for starting up a TV viewing application, and an icon Iq for starting up a video replay application are displayed. As shown herein, since it is highly likely that an image handling application will require a relatively large screen, there is a high probability that the portable terminal will be used sideways. The case in which the portable terminal is held sideways makes it easy to access icons I for starting up applications having a high possibility of sideways use. Therefore, the user may start up a desired application more quickly.

(4-3. Example of Operation)

Herein, an example of an operation in an unlock and an application start-up of the portable terminal 400 according to the present embodiment will be described with reference to FIG. 19. FIG. 19 is a flow chart illustrating an example of an operation of the portable terminal according to the same embodiment.

First, the control unit 407 determines whether or not a screen touch is detected by the touch sensor 105 (S401). If the screen touch is detected, the control unit 407 then determines whether or not a manipulation of pressing and holding the detected touch position without changing over a predetermined period of time is detected (S403). If the press-and-hold manipulation is detected in step S403, the control unit 407 then acquires a direction of a case from the case direction detection unit 413 and selects a set of icons to be displayed based on the acquired direction (S404). Then, the control unit 407 displays the selected icons I radially from the detected touch position (S405).

Then, the control unit 407 determines whether or not a drag manipulation indicating a direction is detected within a predetermined period of time (S407). If the drag manipulation is detected within the predetermined period of time, the control unit 407 starts up an application depending on the direction of the drag manipulation (S409). For example, if one icon I is specified by the drag manipulation, the control unit 407 may start up an application corresponding to the specified icon I. In addition, if no icons I are specified by the drag manipulation, the control unit 407 may start up a home application.

5. Fifth Embodiment

Next, a portable terminal 500 according to a fifth embodiment of the present disclosure will be described. Although different embodiments of how to select icons to be displayed have been described in the first to fourth embodiments, the present embodiment is different from the first to fourth embodiments in an unlock method. Also, in the fifth embodiment, a method of selecting icons to be displayed may take any configuration of the first to fourth embodiments. In the following description, the difference will be mainly described and the common configuration will not be described.

First, a schematic configuration of a portable terminal 500 according to the present embodiment will be described with reference to FIG. 20. FIG. 20 is a functional block diagram of the portable terminal according to the fifth embodiment of the present disclosure.

As illustrated in FIG. 20, the portable terminal 500 according to the fifth embodiment of the present disclosure mainly includes a display unit 103, a touch sensor 105, and a control unit 507.

In the first to fourth embodiments, the unlock manipulation is performed by a press-and-hold manipulation at an arbitrary point on a display screen. However, in the present embodiment, an unlock pattern is used. When the unlock pattern as described herein is used, a pattern connecting a plurality of points displayed on the display screen is compared with a pattern pre-registered as a pattern for unlock, and a lock is unlocked if they match. By such a configuration, the lock may be unlocked only when a user is identified as an owner of the portable terminal 500. Also, the pattern used herein is a pattern that may be drawn in one stroke.

The control unit 507 has a function of controlling the overall operation of the portable terminal 500. For example, the control unit 507 may function as a display control unit that controls contents of a display screen to be displayed on the display unit 103 based on position information of the manipulation body input from the touch sensor 105. Also, the control unit 507 may function as an authentication unit that identifies an owner of the portable terminal 500. For example, when a screen touch on a display screen in a locked state is detected, the control unit 507 may check whether or not an unlock pattern is set. When the unlock pattern is set, the control unit 507 displays an unlock pattern input screen. When an input manipulation is performed on the input screen, the control unit 507 compares an input pattern detected by the touch panel 105 with a pre-registered pattern. As the comparison result, if the two patterns match, the control unit 507 displays icons I arranged radially around a last point of the input pattern. Also, if a drag manipulation on any one of the displayed icons I is detected, the control unit 507 may start up an application corresponding to an icon I specified by the drag manipulation. Although the touch panel display 105 is described as requiring a touch, the display may also be a proximity display device that allows a user to interact with the display without needing to physically touch the display.

Also, as described above, the portable terminal 500 may use any method of the first to fourth embodiments to display icons I. That is, the portable terminal 500 may display at least one of the number of new information and a part of contents on a screen displaying icons I. Also, when the unlock pattern is not set, the portable terminal 500 may divide the display screen into a plurality of areas and display different icons I in each area. Also, the portable terminal 500 may further include the configuration of the position information acquisition unit 209 and select icons I to be displayed based on the acquired position information. Alternatively, the portable terminal 500 may include the configuration of the behavior recognition unit 311 and select icons I to be displayed based on the acquired recognition result. Also, the portable terminal 500 may include the configuration of the case direction detection unit 413 and select icons I to be displayed depending on the direction of the case.

The example of the functions of the portable terminal 500 according to the present embodiment has been shown above. The respective elements described above may be configured using general-purpose members or circuits, or may be configured by hardware specialized in the functions of the respective elements. Also, an arithmetic device, such as a central processing unit (CPU) or the like, may perform the functions of the respective elements by reading a control program from a storage medium, such as a read only memory (ROM), a random access memory (RAM), or the like, which stores the control program describing a processing procedure of realizing these functions, and by interpreting and executing the program. Therefore, the configuration to be used may be appropriately modified depending on a level of technology when the present embodiment is implemented. Also, an example of a hardware configuration of the portable terminal 500 will be described later.

Also, a computer program for realizing the respective functions of the portable terminal 500 according to the present embodiment described above may be created and implemented on a personal computer or the like. Also, a computer-readable recording medium on which such a computer program is stored may also be provided. The recording medium may be, for example, a magnetic disk, an optical disc, a magneto-optical disc, a flash memory, or the like. Also, the computer program may also be delivered through a network, without using the recording medium.

(5-1. Example of Display Screen)

First, an example of a display screen displayed on the display screen 103 of the portable terminal 500 according to the present embodiment will be described with reference to FIG. 21. FIG. 21 is an example of a display screen for performing an unlock manipulation, including an owner identification (or authentication), which is displayed on the portable terminal according to the fifth embodiment of the present disclosure.

For example, as illustrated in FIG. 21(A), it is assumed that when the control unit 507 displays the unlock pattern input screen, the user draws a pattern as indicated by arrows. In this case, the control unit 507 compares the input pattern with the pre-registered pattern. If the input pattern matches the pre-registered pattern, the control unit 507 displays icons I radially around a last point P2 of the pattern (FIG. 21(B)). Herein, if the user performs a drag manipulation on any one of the displayed icons I (FIG. 21(C)), an application corresponding to an icon I of a direction in which the drag manipulation is detected is started up, as with the first to fourth embodiments.

(5-2. Example of Operation)

Herein, an example of an operation in the unlock and the application start-up of the portable terminal 500 will be described with reference to FIG. 22. FIG. 22 is a flow chart illustrating an example of an operation of the portable terminal according to the same embodiment.

First, the control unit 507 determines whether or not a screen touch is detected by the touch sensor 105 (S501). Then, the control unit 507 determines whether or not an unlock pattern is set (S502). Herein, if the unlock pattern is set, the control unit 507 displays the unlock pattern input screen on the display unit 103 (S505). If the user performs the input manipulation on the input screen, the control unit 507 compares the input pattern with the pre-registered pattern and determines whether or not the unlock pattern is input correctly (S507). In step S507, if it is determined that the unlock pattern is input correctly, then the control unit 507 displays icons I radially from the detected touch position (herein, the last point of the unlock pattern) (S509).

On the other hand, in step S502, if it is determined that the unlock pattern is not set, then the control unit 507 determines whether or not a press-and-hold manipulation is detected by the touch sensor 105 (S511). Herein, if the press-and-hold manipulation is detected, the control unit 507 displays icons I radially around the detected touch position (herein, pressed-and-held point).

Then, the control unit 507 determines whether or not a drag manipulation is detected within a predetermined period of time (S513). If the drag manipulation is detected in step S513, the control unit 507 starts up an application depending on the direction of the drag manipulation (S515). For example, if one icon I is specified by the drag manipulation, the control unit 507 may start up an application corresponding to the specified icon I. In addition, if no icons I are specified by the drag manipulation, the control unit 507 may start up a home application.

The portable terminal 500 according to the fifth embodiment of the present disclosure has been described above. According to such a configuration, even when the application is started up after the unlock manipulation of performing the owner identification, manipulability may be improved. In particular, according to the configuration in which icons I are displayed radially around the last point of the unlock pattern performing the owner identification by the pattern drawn in one stroke, the unlock to the application start-up may be performed by a series of manipulations (without lifting a finger from a manipulation screen).

6. Example of Hardware Configuration

In the portable terminal 100, the portable terminal 200, the portable terminal 300, the portable terminal 400, and the portable terminal 500 according to the first to fifth embodiments of the present disclosure described above, the configurations appropriate to use may be selected depending on the level of technology when the present embodiments are implemented as described above. Herein, an example of a hardware configuration for realizing the functions of the portable terminal 100, the portable terminal 200, the portable terminal 300, the portable terminal 400, and the portable terminal 500 will be described with reference to FIG. 23.

The GPS antenna 821 is an example of an antenna that receives a signal from a positioning satellite. The GPS antenna 821 may receive GPS signals from a plurality of GPS satellites, and input the received GPS signals to the GPS processing unit 823.

The GPS processing unit 823 is an example of a calculation unit that calculates position information based on the signal received from the positioning satellite. The GPS processing unit 823 calculates current position information based on the plurality of GPS signals input from the GPS antenna 821, and outputs the calculated position information. Specifically, the GPS processing unit 823 calculates the positions of the respective GPS satellites from orbital data of the GPS satellites, and calculates each distance from the respective GPS satellites to the corresponding terminal device 100 based on a difference time between a transmission time and a reception time of the GPS signal. Then, a three-dimensional current position may be calculated based on the calculated positions of the respective GPS satellites and the distance from the respective GPS satellites to the corresponding terminal device 100. Also, the orbital data of the GPS satellites used herein may be included in, for example, the GPS signals. Alternatively, the orbital data of the GPS satellites may be obtained from an external server through the communication antenna 825.

The communication antenna 825 is an antenna that has a function of receiving a communication signal through, for example, a portable communication network or a wireless local area network (LAN) communication network. The communication antenna 825 may provide a received signal to the communication processing unit 827.

The communication processing unit 827 has a function of performing a variety of signal processing on the signal provided from the communication antenna 825. The communication processing unit 827 may provide the CPU 839 with a digital signal generated from a received analog signal.

The geomagnetic sensor 829 is a sensor that detects geomagnetism as a voltage value. The geomagnetic sensor 829 may be a triaxial geomagnetic sensor that detects geomagnetism of each of an X-axis direction, a Y-axis direction, and a Z-axis direction. The geomagnetic sensor 829 may provide the CPU 839 with the detected geomagnetic data.

The acceleration sensor 831 is a sensor that detects acceleration as a voltage value. The acceleration sensor 831 may be a triaxial acceleration sensor that detects each of acceleration along an X-axis direction, acceleration along a Y-axis direction, and acceleration along a Z-axis direction. The acceleration sensor 831 may provide the CPU 839 with the detected acceleration data.

The gyro sensor 833 is a type of measuring equipment that detects an angle and an angular velocity of an object. The gyro sensor 833 may be a triaxial gyro sensor that detects a changing velocity (angular velocity) of a rotational angle around an X axis, a Y axis, and a Z axis as a voltage value. The gyro sensor 833 may provide the CPU 839 with the detected angular velocity data.

The atmospheric pressure sensor 835 is a sensor that detects an ambient pressure as a voltage value. The atmospheric pressure sensor 835 may detect an atmospheric pressure at a predetermined sampling frequency and provide the CPU 839 with the detected atmospheric pressure data.

The imaging unit 837 has a function of capturing a still image or a moving image through a lens according to the control of the CPU 839. The imaging unit 837 may store the captured image in the storage unit 859.

The CPU 839 functions as an arithmetic processing device and a control device and controls the overall operations of the portable terminal 100, the portable terminal 200, the portable terminal 300, the portable terminal 400, or the portable terminal 500 according to various types of programs. Also, the CPU 839 may be a microprocessor. The CPU 839 may realize various functions according to various types of programs.

The ROM 841 may store programs and arithmetic parameters the CPU 839 uses. The RAM 843 may temporarily store programs used to execute the CPU 839, parameters changed appropriately for the execution thereof, or the like.
